When it comes to infrastructure validation, most of the time, organizations focus on validating a happy path where everything is working. Instead, you should validate how your system fails and how well your recovery procedures work. Validate your application, assuming everything fails all the time. Don't just expect that your recovery and failover strategies will work. Make sure to test them regularly, so you're not surprised if something does go wrong.
A simulation-based validation helps you to uncover any potential risks. You can automate a possible scenario that could cause your system to fail and prepare an incident response accordingly. Your validation should improve application reliability in such a way that nothing will fail in production.
Recoverability is sometimes overlooked as a component of availability. To improve the system's Recovery Point Objective (RPO) and Recovery Time Objective (RTO), you should back up data and applications...
